Abstract: An endoscope has an insertion portion inserted through a living body, an illumination fiber arranged at a distal end of the insertion portion and irradiates the living body with illumination light, a detection fiber which detects return light from the living body, an actuator which swings a free end of the illumination fiber, and a ferrule which has a through-hole based on a diameter of the illumination fiber and is arranged between the illumination fiber and the actuator. The actuator has an actuator arranged at a first side face of the ferrule and an actuator arranged at a second side face of the ferrule that is different from a face point-symmetric to the first side face with respect to an axial direction of the illumination fiber.
